The benefit of achieving asynchronous processing. This gives you:

• Number one is the comfort of your system being stable and running in a very reliable way. Therefore, you'll have very minimal downtimes, which means more revenue for you.
• If you're able to set it up correctly on-prem, then it actually becomes a one-time cost, actually, installation. So you don't need to pay for it ongoing. That means your revenues even become higher. 
• But if you lack the technical capacity, you can purchase a managed instance from Microsoft, AWS, GCP –  cloud-managed. By the time you're going to those platforms, I think you have enough revenue to pay for the cost. But you will also get a very higher rate of uptime.
